CURRENT-MOTOR.

SPECIFICATION forming part of Letters Patent No. 283,769, dated August28, 1883,

Application filed July 26, 1852.

To all whom it may concern.-

Be it known that I, ALBERT D. GARRET- soN, a citizen of the UnitedStates, residing in the city of Buffalo. county of Erie, and State ofNew York, have invented certain new and useful Improvements inWatenMotors, of which the following is a specification.

The nature of my invention relates to certain new and usefulimprovements in that class of motors which are designed to be driven bythe impact of currents of wind or water without the employment of damsor other obstructions, except such as is offered by the motor whenexposed or submerged.

The invention consists of a combination of endless belts or chainssupported by a suitable frame, adapted to lie across the currents andcarrya series of hinged wings, so arranged that the wings will receivethe impact of the currents alternately on opposite faces, and thusutilize continuously all of the wings.

Figurelisafront elevation, and Fig. 2 a sectional perspective.

In the accompanying drawings, A A are reversing-wings, hinged at y y y yto the endless chains w w w w, and connected by short chains at theirouter or movable edges, 12 o, to the axis of the next wing, and ofsufficient length to hold the wings in the proper position and angle.The current, moving in the direction of the arrow a in Fig. 2, willstrike all the wings first at a a, causing them to move in the directionof the arrow 0, and, being deflected by such impact, striking the secondor returning series of wings at a a, and

] causing them to move in the direction of the arrows o c.

S S S S are drums to support the chains and wings, and R is a drum forthe transmission of power.

When driven by water, it is preferable tha the whole be submerged to asufficient depth to avoidice, drift-wood, or other obstructions.

WVhat I claim as my invention is 1. The drums S, suitably journaled inthe frame and carrying the endless chains, in combination with a seriesof reversing-wings ing connected by short chains, one end of each ofwhich is secured to-the free or outer edges of the wings, and the otherend to the axis of the wing next in series, substantially as and for thepurposes described.

2. A water-motor wherein the series of reversing-wings are pivotallysecured at their rear corners to endless chains running over drums journ aled on opposite ends of the frame, said wings being securedtogether by chains connecting the front edges to the rear edges thereof,and arranged relatively to each other to receive the force of thecurrent continu-. ously and directly on a portion of the wings, andthen, by deflection upon another portion of the wings. running in anopposite direction, substantially as specified.
